The LT1359IS#PBF is a popular instrumentation op amp that is widely used in data acquisition and measurement systems. It is a low cost, high accuracy, single-supply instrumentation amplifier with an adjustable gain range of 1 to 1,000,000 and a unity gain frequency of 1 kHz. It is designed to provide both accurate measurements and low noise performance. The LT1359IS#PBF has an offset voltage of 2.5 mV and an input impedance of 1 megohm. It is also available with an output offset voltage trim and differential non-inverting inputs.

The LT1359IS#PBF is ideal for applications where a low noise, high accuracy instrumentation amplifier is needed. It is well suited for use in medical diagnostics, industrial control and data acquisition, test and measurement systems, and consumer electronics. It is also suitable for applications requiring precision measurements and low power consumption.

The LT1359IS#PBF is an ideal choice for multiplexed data acquisition systems. It can handle very large input voltages and provide accurate conversion from the analog world to the digital one. The op amp has excellent high frequency performance that allows for fast and accurate conversion. The amplifier can also provide up to 70 dB of gain at frequencies as low as 0.2 Hz.

The LT1359IS#PBF is designed with a low input bias current to reduce errors due to current injection from external circuit and control signals. This feature provides improved accuracy and stability in long-term DC measurements. The high common-mode rejection (CMR) of up to 100 dB ensures that signals that are common to both the inverting and non-inverting inputs are rejected, preventing errors and improving accuracy.

The LT1359IS#PBF working principle centers on its use of a differential amplifier stage to measure differences between two input signals. Two separate inputs are used to sense different input signals, which are then converted to a single output signal. The input is amplified by passing through two differential inputs and then regenerated through a current feedback loop.

The current feedback loop is used to balance the effects of the input resistance variation on the amplifier gain. This is accomplished by adding a current source to the amplifier\'s output, thus providing a very low input offset voltage, current, and drift. The output current source also provides excellent power supply rejections and reduces distortion, allowing for accurate signal measurements.

The LT1359IS#PBF provides low noise performance, high accuracy, and wide dynamic range, making it the perfect choice for instrumentation applications. It is ideal for use in medical diagnostics, industrial control and data acquisition, test and measurement systems, and consumer electronics. It can also be used for precision measurements and low power consumption.
